Both of them have their own pros and cons: G data edge F secure .
Pros: Both are dual engine, however F secure 98% of cases depends on BD, that is not case in G data.
Repair capability of G data, over F secure quarantine ability.
G data removal capability against unknown malware is quite good, F secure is very very poor here.
F secure lack roll back capability over G data.
G data has pro active modules like Bank guard, Deep ray , which F secure lacks.
F secure doesn't have boot time protection lacks own firewall, own signatures.
F secure has good anti phishing compared to G data.
Choose accordingly.F secure really improved on Fp's, Deep guard.
I choose G data for above reasons!
